AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 1016 PM CDT Mon Jun 1 2020

Discussion. Issued at 238 PM CDT MON JUN 1 2020

Message of the Day: Our first wave of summer temperatures arrives tomorrow. Multiple days of temperatures in the upper 80s to low 90s with heat indices in the low to mid 90s are expected. Given the cooler spring, extra precaution needs to be taken when outdoors this week. Make sure to drink plenty of water and take frequent breaks to remain safe.

Happy Meteorological Summer! And the summer weather is showing up right on time, with a rather large upper level ridge has taken shape over the central part of the country, and southwesterly flow tapping into the Gulf of Mexico. These features will help warm and humid air advect into our area. Today will be a stepping stone, with highs in the low to mid 80s and really no heat index. Tomorrow is the beginning of the upper 80 to low 90 degree temperatures with heat indices in the low to mid 90s. These temperatures and heat indices are expected to last at least through the end of the weekend. No heat products are expected to be issued at this time, since we are forecast to stay well below thresholds. However, caution must be taken when outside this week given this is the first time we will see these warm temperatures and the warm temperatures will stick around for a prolonged period of time. If you do spend some time outside this week, make sure you drink plenty of water and take frequent breaks inside or in the shade.

We will see a slight break down of the upper level ridge on Wednesday and Thursday as a shortwave trough moves through the Midwest. At the surface, a cold front will move into northern MO, eventually stalling across MO (at least right now). This will be the focus point for storm chances Wednesday into Thursday. Some storms could become strong to severe Wednesday afternoon and evening with ample instability (~3000 J/kg) across the area. Shear won't be as impressive though (~25 kts), so widespread severe weather is not expected right now. Main concerns are strong winds and hail. Moderate to heavy rainfall is also possible with PWATs well above normal, so we may have some flooding concerns as well. Storm chances, albeit smaller chances, will linger into Thursday and Friday as well as additional shortwave troughs run the upper level ridge. These rain chances and cloud cover may limit some temperatures, mainly across northern MO, but above normal temperatures are still expected.

Warm temperatures will continue for the weekend as the upper level ridge moves back over the central U.S.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
